Quota based on Transportation lane in SNP Heuristics

Hi All,

We are in SCM 5.0 and are planning to use SNP Heuristic only (no Optimizer).

A particular location A can receive from a source location B by two means of transport Air and Sea. The lead times are 5 days and 60 days respectively. We want to supply 40% by Air and 60% by Sea. We have created two transport lanes between A and B and are able to maintain these percentages as Quotas.

What are the steps, if any, so that SNP Heuristic run can propogate the demand at location A based on these quota to location B? That is, we want the requirement of A to be split into two based on the lead times.

Thanks in advance.
